$ xvinfo
X-Video Extension version 2.2
screen #0
 no adaptors present

$ glxinfo | grep OpenGL
OpenGL vendor string: Mesa project:
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.4 (2.1 Mesa 7.0.3-rc2)
OpenGL extensions:

Followed by the usual...
make install

I haven't upgraded to 1.3 yet.
